Other findings also were neutral. Voters split on which party should control the Senate. Democrats now control 55 of the 100 seats. Forty-six percent wanted Democrats to control the House--now run by Republicans--and 45 percent wanted continued GOP control.

Other key findings:

--"American voters oppose the Affordable Care Act 55 – 41 percent and 40 percent are less likely to vote for a candidate who supports Obamacare, while 27 percent are more likely and 31 percent say this will not affect their vote.

--"Immigration also is a possible pitfall for candidates, as 39 percent of voters say they are less likely to vote for a candidate who supports a path to citizenship for illegal aliens, while 29 percent are more likely and 29 percent say it won’t make a difference in their vote.
